i Application iiled March 25, 1898. Serial No. 675,158. (SpecimensJr To all whom it may concern:

Y Be it known that we, THOMAS BENTON DOR- and useful Improvements in ingrain Carpet Fabrics, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.

Our invention relates to ingrain carpet fabrics, and has for its object to increase the pattern and color capabilities of such fabrics. According to our invention additional warpthreads are provided which are not dependent upon or subject to the arrangement of weft-threads, as are the regular warp-threads, but may be brought to the surface at any time or in any color eect, and when thus brought to the surface pass from ply to ply, covering all weft-threads and producing embossed effects solely of the color or colors of the additional warp-threads. These additional warp-threads may be larger or of greater diameter than the regular warp-threads and by covering and concealing the weft-threads and regular warp-threads may be made the only visible threads at portions of the fabric, and thus solid color effects may be produced of the color or colors of the .additionalv warp-threads. These additional warp-threads maybe of different colors along different longitudinal lines, and in a suitable pattern these additional colors may be brought to the surface, so as to produce handsome colorings 'of great variety.

We will now describe our invention, 4more particularly referring to the accompanying drawings, representing fabrics embodying our invention.

In all of the drawings fabrics or portions of fabrics are diagrammatically represented containing the ordinary four sets Aof warpthreads and figuring weft-threads arranged ditional warp-threads to produce an effect of the colors of the additional warp-threads. Fig. 2 is a plan or face view of the same. Fig. 3 is a longitudinal section showing the ordinary warp and weft threads arranged as in the effect ground up, but covered by the additional warp-threads. Fig. 4 is a similar section of the effect ground up and an effect of the additional warp-threads with the ordinary warp-threads between the plies Where the additional warp-threads pass from ply to ply and cover the weft-threads.

The several figuring weft-threads are indicated in the drawings by the letters WV B R O and may be, respectively, of the colors white, black, olive, and red, the color being indicated by the initial letter. The ordinary warp-threads are indicated by the letters w b `ro and maybe, respectively, of the colors' above named, the color being indicated by the initial letter.

The numerals 1 2 3 Lidesignate the figuring weft-threads in the sequence of weft-shots in eachv set.

The additional warp-threads are represented in the drawings by a heavier line than the ordinary warp-threads or by double lines, and we propose to employ for the additional warp-threads a yarn heavier or larger in diameter than that employed for the ordinary warp-threads.

The additional warp-threads are indicated bythe characters r and s. The character r appears in all views of 'the drawings and lmaybe taken as indicating that `the additional warp-threads so designated are of red color. The character s appears only in Fig. 2 to designate additional warp-threads arranged similarly to the additional warpthreads fr', but of a different color, as seadrab.

The additional warp-threads are preferably arranged with two ordinary Warp-threads intervening between each additional warpthread, as shown in Fig. 2, in which case with a reed which included four ordinary Warp-threads in each split thereof there would be two additional warp-threads to each split of the reed. The additional warp-threads should usuallybe controlled by the jacquard mechanism, and as they are not necessarily IOO associated with any particular weft-'thread or weft-threads, and are not required to bind the weft-threads, as are the -ordinary Warpthreads, they may be brought tothe surface independently of the arrangement of Wef threads and regular Warp-threads. Y

According to our invention the additional Warp-threads, Where desired in the pattern, are passed from ply to ply, covering all weftthreads, tightly tying the plies together, and producing an embossed eect wherein all other threads are concealed, so that Where the" additional Warp-threads are all of one color a solid effect of that color is. produced, and thus the fabric may be provided with solidcolored portions of a color entirely different and, if desired, in striking contrast with ordinary colorings produced by the variations of Weavin g of the ordinary Warp-threads and weft-threads. The ordinary color effects of the fabric are not changed and the ordinary construction of the fabric is not changed in any part of the fabric in the constructions -shown in Figs. 1 to 3, inclusive. The additional Warp-threads may be allowed to oat between the plies where they are not required on the surface or may be cut off at suitable distances on either side of their exposed portions, as desired.

Where the ordinary Warp-threads are not controlled by journals orby other means compeiling the lifting of all regular Warp-threads of one color when the 'weft-thread of corresponding color is shot, a variation of strucemployed. We do not therefore limit'our invention to the particular construction shown; but

" What We claim, and desire to secure by Letters Patent, is= 1. An ingraiu carpet fabric composed of Warp-threads and figuring weft-threads and also containing additional Warp-threads, said fabric exhibiting at parts thereof color ef-A fects produced by said Warp-threads and figuring'Weft-threads and said fabric exhibiting at the other parts thereof color effects solely of the color or colors ofthe additional Warpthreads, said additional Warp-threads at the parts of the fabric Where they are thus exhibited passing from ply to ply so as to cover all weft-threads, substantially as set forth.

2. An ingrain carpet fabric composed of figuring Warp threads and figuring weftthreads and also containing additional Warpthrea'ds, said figuring Warp-threads and figuring Weftsthreads being interwoven throughout the fabric and said fabric exhibiting at parts thereof color effects produced by said figuring Warp threads and figuring weftthreads and said fabric exhibiting at other parts thereof color effects solely of the color or colors of the additional Warp-threads, said additional Warp-threads at the parts of the fabric where they are thus exhibited passing from ply to ply so as to cover all weft-threads, substantially as set forth.-
